South Korean site Hardware Battle in late July published a screenshot of Cinebench R15, obtained while testing the engineering sample of the six-core processor Coffee Lake, which was overclocked to 5.0 GHz with a voltage on the 1.4 V core.

Apparently, either air cooling or liquid cooling was used. Note that in the CPU-Z test, the Coffee Lake processor with six cores and Hyper-Threading scored 4467.4 points, and the eight-core AMD Ryzen 1700X received 4271 points. If we talk about Cinebench R15, then Coffee Lake at a frequency of 5.0 GHz scored 1591 points.
